Services
We understand that a motor breakdown can have far-reaching effects on your business. Downtime and loss of production are obviously key factors, and after initial analysis we can advise you on repair or replacement depending on the most cost effective option. With a wealth of experience of motor repairs and motor rewinds, our skilled team of engineers provide a comprehensive repair, overhaul and in-house electro-engineering service.
Infrared Thermography is a technique that is used to gather thermal information from any object or area by temperature and converting it into a visual image. We use troubleshooting tools that can help you find and report equipment problems fast. That's exactly what our Flir T4 Series thermographic camera does.
To ensure compliance with current legislation, a regular program of test and inspection of all electrical installations must be implemented within a non-domestic environment. These tests ensure that all necessary precautions have been taken to reduce the risk of electrical failure which could ultimately lead to injury or death.
Our team of skilled electrical engineers design and build electrical panels and perform electrical installation of industrial equipment. We are able to provide a complete control panel manufacturing and electrical installation service. LER work to a wide variety of customer specifications and the engineering standards laid out in the 17th Edition.
Machine breakdown is often the result of additional wear and tear caused by shaft misalignment. Angular or parallel shaft misalignment places additional and unequal strain on moving parts. Misalignment also increases energy consumption and increases running costs. Laser Alignment is the perfect solution to this problem and combined with a thermographic inspection, LER can identify machinery parts that are at risk.
